I've just uploaded a better Windows InstallShield for GHC that fixes a
problem with the last one, but more importantly, hides the Cygwin binaries
it installs in ghc-4.08.2/extra-bin, so that they do not interfere with, and
are not intefered with by, any installation of Cygwin you may have on your
system.
Incidentally, I have also fixed a small problem in the Happy InstallShield,
so if you couldn't get it to work, try downloading again.
